Arctic Tundra

Introduction

Introduction

Our project is based on the arctic tundra biome. This biome is among Earth's coldest and harshest biome's. It's located in the northern and southern hemisphere of the world. Hope you enjoy our presentation.

Biome Characteristics

Biome

Characteristics

Climate

Tundra's are among Earth's coldest biome's, so climate in most Arctic Tundra's are cold and windy. But rain is very minimum.

climate

Precipitation

There is very little precipitation in the Arctic Tundra because it rarely rains and since weather conditions are really harsh and cold. Yearly precipitation, including melting snow, is 6 to 10 inches. Soil is formed slowly.

Precipitation

Average Temperature

The average temperature in the arctic tundra is the average winter temperature is -25 degrees C, and in the summer it is rarely over 10 degrees C.

Are there seasons?

The growing summer season in the arctic tundra only lasts 50-60 days. most of the time during the summer it's cloudy and their is a lack of nutrients. In the winter it's mostly dark and can become -25 degrees Fahrenheit.

Are there Seasons?

Locations in the world

Tundra regions are found in the northern and southern hemispheres of the world. Between the ice-covered poles and the taiga or coniferous forests.

Plants in the Tundra

Plants

A few plants from the Arctic Tundra are Arctic Moss, Arctic Willow, Caribou Moss, and Bearberry.

Arctic Moss

The arctic moss is a plant that can grow all year long. It can grow on the surface, but its primarily an aquatic plant that grows beneath the surface of the water.

Arctic Moss

Arctic willow

The arctic willow is a plant that is found growing on the bottom of tundra lake beds and in and around bogs and fens. They have many different shapes, but they usually have long trailing branches that root when they touch the surface.

Arctic Willow

Caribou Moss

Caribou Moss grows on the ground and on rocks. It looks like foamy, gray-green spongy moss. It's actually a lichen that can grow to be 1 to 4 inches tall.

Caribou Moss

Bearberry

This plant adapts to the Arctic Tundra by it's leathery leaves that help it survive the cold. Also by its fine silky hairs. This plant is a low growing plant.

Bearberry

Animals

Animals

-Polar bear

-Arctic Hare

-Snowy Owl

-Arctic Fox

-Rock Ptarmigan

Polar Bear

Polar Bears

Lives in

-Canada

-Alaska

-Russia

-Norway

Habitat

Polar Bears eat a lot of food items, but their main food source is seals.

Food

Polar Bears weigh a lot.

Weight and height

-They are among the largest mammal's on Earth.

-They weigh anywhere from 700-1400 pounds.

Arctic Hare

Habitat

Arctic Hare only live in Northern Canada and various part of Greenland.

Food

Arctic Hare eat

-buds

-berries

-twigs

-mosses

-woody plants

Weight and Height

Arctic Hare are 20-26 inches tall, and 8-14 pounds.

Snowy Owl

Habitat

Snowy Owls are circumpolar, so they are found in Alaska, Canada, Greenland, Russia, and, many other areas of the Arctic Circle.

Snowy Owls eat small Rodents.

Food

Snowy Owls are 1.75-2 feet lengthwise, 4.5-5.5 feet wingspan.

Weight and Height

Arctic Fox

Arctic Fox are also circumpolar and are found throughout the Arctic region.

Habitat

Arctic Fox eat small mammals including

-voles

-lemmings

-birds

-birds eggs

Food

Arctic Foxes weigh 6-9 pounds, and they are 3-3.5 feet in length.

Weight and Height

Arctic Foxes live in a harsh environment. They have certain adaptations that help them survive, like their thick fur and fluffy tail help them to not freeze.

Adaptation

Rock Ptarmigan

Habitat

Rock Ptarmigans are also circumpolar, so they can be found in the north of the the Arctic Circle, including

-Russia

-Sweden

-Canada

-Iceland

-Greenland

Rock Ptarmigans are pigs.

Food

-Leaves

-flowers

-berries

-buds

-twigs

-other vegetables.

Rock Ptarmigans are little, they are 12-16 inches in length, and they weigh only 0.03 pounds.

Threats

Threats of the Tundra

1. Global Warming

2. Oil spills

3. Buildings and Roads

4. Invasive species

global warming

Global warming

The melting of permafrost, which contains carbon dioxide, a greenhouse gas, could result to global warming and that could damage the landscape and the animals.

Oil spills

Oils spills can kill the wildlife which can drastically change the ecosystem.

Oil spills

Buildings and roads

Buildings and roads put heat and pressure on the permafrost causing it to melt and letting the greenhouse gas out into the air.

Buildings and roads

Invasive species

Invasive species push aside native vegetation and reduce diversity of plant coverage. Invasive species in the arctic tundra include: Japanese Ghost Shrimp and the Club sea-squirt.

Invasive species

Why would you go there?

Even though it's extremely frigid in the Arctic Tundra it's a cool experience to see all of the cool animals and plants that live there. Since, most of those animals can't live in normal climates that you usually live in. It's something you can only see in an arctic tundra.
